1×6 and 1×8 T&G Premium Fir

An excellent choice for projects requiring a seamless finish, tongue-and-groove premium fir hides nails with an overlapping pattern. Douglas Fir is known for its warm hues and remarkably straight grain, ideal for interior finish applications. It is the highest-rated North American softwood in strength-to-weight ratio and stiffness.


Builders use it for interior applications such as doors, windows, cabinets, stairs, flooring, molding, trim, and ceilings. Douglas Fir is durable and can work for exterior applications, such as porch flooring, decking, fascia, trim, and siding.


You can buy Tongue and Groove Premium Fir from Reliance Timber in 1×6 and 1×8 sizes.
